136 Q9 ASD Installation and Operation Manual
Annual Average Ambient Temperature
No Path — Direct Access Only
This parameter is used in conjunction with a discrete output terminal setting to
notify the operator of the remaining useful life of critical components of the ASD
system.
With a discrete output terminal set to Part Replacement Alarm (see Table 7 on
pg. 190) and the calculation derived from the parameter setting, maintenance
scheduling may be enhanced.
Settings:
1 — Under 10° C (50° F)
2 — Under 20° C (68° F)
3 — Under 30° C (86° F)
4 — Under 40° C (104° F)
5 — Under 50° C (122° F)
6 — Under 60° C (140° F)
Direct Access Number — F634
Parameter Type — Selection List
Factory Default — Under 30°
Changeable During Run — No
Rush Relay Current Activation Time
No Path — Direct Access Only
At system startup, this parameter sets a time-delay for the start of the Rush Relay
activation in an attempt to allow the DC bus voltage to reach the normal operating
level before outputting a signal to the motor.
Direct Access Number — F635
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — No
Minimum — 0.0
Maximum — 2.5
Units — Seconds
PTC1 Thermal Selection
No Path — Direct Access Only
This parameter Enables/Disables the optional external thermal detection circuit
of the Expansion IO Card Option 1. A thermistor is connected from TH1+ to
TH1- of TB3 on the Expansion IO Card Option 1.
Should the thermistor resistance reading fall below 50Ω because of an over-
temperature condition or exceed 3000Ω because of an open circuit an External
Thermal Fault (OH2) will be incurred.
Note: While this parameter is Enabled, the system cannot be restarted
until the thermistor value recovers to the level of 1.8kΩ from an
over-temperature condition. An Auto-Restart will not be initiated
subsequent to an External Thermal Trip (OH2). A manual restart
will be required in the event of an OH2 trip.
Settings:
0 — Disabled
1 — Detect Disconnect
Direct Access Number — F637
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
